In this tutorial, we will show you how to backup and restore the MySQL database using Command-Line. For those of you who didn’t know, MySQL is an open-source database developed by Oracle whereas MariaDB is a fork of it that works similarly and uses the same command line as MySQL.
This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘
sudo‘ to the commands to get root privileges. I will show you through the step-by-step installation of backup and restore MySQL on a Linux server.
The parameters of the said command as follows.
uname] Your database username.
passwd] The password for your database (note there is no space between -p and the password).
dbname] The name of your database.
backupdb.sql] The filename for your database backup.
Backup and Restore MySQL Database Using Command Line
Backup MySQL database
First, you can check MySQL databases from your server:
#mysql -h localhost -u root -p #mysql> show databases;
The following command will dump all databases into an SQL file. Replace pass with your root database password and filename with the name of the file you wish to create such as backupdb.sql
Back up multiple databases in MySQL
$ mysqldump –u[uname] –p[passwd] [database name 1] [database name 2] > backup.sql
$ mysqldump –u root –pidroidus chedelics radiks > backup.sql
Backup all databases in MySQL
$ mysqldump –u [uname] –p[passwd] –all-databases > backup.sql
$ mysqldump –u root –pidroidus –all-databases > backup.sql
Back up your MySQL Database with Compress
$ mysqldump -u root -p[passwd] --databases [dbname] | gzip > backup.sql.gz
$ mysqldump -u root -pidroidus --databases | gzip > backup.sql.gz
Restore MySQL database from a backup file
Above we backup the Tutorials database into backupdb.sql file. To re-create the Tutorials database you should follow two steps:
- Create an appropriately named database on the target machine
- Load the file using the
$ mysqladmin -u root -p create [dbname]
$ gzip -d backupdb.sql.gz #mysql -uroot -p[passwd] [dbname] < backupdb.sql
$ mysqladmin -u root -p create chedelics $ gzip -d backupdb.sql.gz $ backupdb.sql $ mysql -uroot -pidroidus chedelics < backupdb.sql
